NLS-research of the eyebulb and orbital cavity was performed in M. D. Anderson Cancer Center using Metatron hunter 4025 with the use of non-linear trigger multi-frequency sensors with 9.6 GHz generator. The system is designed for 2D and 3D researches. Volumetric ultramicroscanning mode, multiplan analysis of the image, interactive 3D-rendering and spectral-entropic analysis of the tissues structure were used during the research. Overlapping mode of volumetric data received in the modes of NLS-image and MRT was used for 3D organ reconstruction procedure. Dynamic multifrequent focusing, panning and scaling (high-resolution) are the parts of the research technology.

    Using such methodological approach allowed studying individual eye elements from the different angles which frequently permitted to «observe» eye corners inaccessible for common ophthalmological examination. Received data archiving was performed using magnetic carriers.

    The examination of both eyebulbs of the patient and comparison of their NLS-graphic image were the obligatory conditions.

    Qualitative and quantitative characteristics of the eye and orbital cavity structures were studied using serial poly-projection NLS-grams.

    Virtual 3D NLS-reconstruction along with relief and form determination of the neoplasm is used for correction of its ratio to the eye and orbital cavity structures. The use of 3D color reconstruction of the vessels helped studying of angioarchitecture of the eye vessels and neoplasm presenting the information concerning the peculiarities of the feeding artery.
